Furthermore, the present invention relates to an antiperspirant cosmetic agent containing at least one antiperspirant compound, optionally at least one propellant and at least one of sheep's wool or goat's wool isolated special keratin. By adding the at least one specific protein, the amount of antiperspirant compound can be reduced without adversely affecting the antiperspirant effect of the cosmetic composition.

Finally, the present invention relates to a non-therapeutic cosmetic method for preventing and / or reducing the transpiration of the body, in which an inventive antiperspirant cosmetic agent or a packaging unit according to the invention is applied to the skin, in particular on the skin of the armpits, and for at least 1 Hour, preferably for at least 2 hours, preferably for at least 4 hours, in particular for at least 6 hours, remains on the skin of the armpits.

Washing, cleansing and caring for one's own body is a basic human need, and modern industry is constantly trying to meet these needs of man in a variety of ways. Especially important for daily hygiene is the permanent elimination or at least reduction of body odor and underarm wetness. Numerous specific deodorant or antiperspirant personal care products are known in the art which have been developed for use in body regions having a high density of sweat glands, especially in the underarm area. These are formulated in a wide variety of dosage forms, for example as powder, in stick form, as aerosol spray, pump spray, liquid and gel roll on application, cream, gel and as impregnated flexible substrates (towels).

Prior art cosmetic antiperspirants contain at least one antiperspirant compound, in particular in the form of halides and / or hydroxyhalides of aluminum and / or zirconium, in addition to at least one oil or a wax and a fragrance component or perfume. These antiperspirant compounds reduce sweat secretion of the body by temporarily narrowing and / or obstructing the excretory ducts of the sweat glands, so that the amount of sweat can be reduced by about 20 to 60 percent. On the other hand, they have an additional deodorizing effect due to their antimicrobial effect.

Halides and / or hydroxy halides of aluminum and / or zirconium, combined with the acidic pH of these antiperspirants, can cause unpleasant skin reactions in some users. In addition, the use of the aforementioned antiperspirant compounds can lead to staining on clothing.

There is therefore a need for the total amount of antiperspirant halides and / or hydroxy halides of aluminum and / or zirconium in antiperspirant cosmetic agents reduce. These antiperspirant agents should have a good antiperspirant effect, good skin compatibility and high storage stability.

It is an object of the present invention to provide a perspiration-inhibiting cosmetic agent which avoids or at least mitigates the disadvantages of the prior art and which has good skin compatibility with at the same time reliable reduction of underarm wetness. In addition, the antiperspirant cosmetic agent should have a high storage stability.

It has now surprisingly been found that by the use of at least one protein from skin appendages of mammals, birds, fish, insects or crustaceans, which with a change in the pH of at least 0.5 in a pH range of pH 4.0 to pH 8.0 causes a change in light absorption of 1 to 100%, in cosmetic products, the total amount of antiperspirant compounds can be significantly reduced without the antiperspirant effect of these agents or their storage stability is adversely affected.
